Question 1.
Define Grashof's Rule.
Show hintHide hint
What condition must be met for continuous rotation?
Question 2.
What does DOF stand for?
Show hintHide hint
Think about independent movements in a mechanism.
3Question 3.
What is Grashof's condition?
- s + l > p + q
- s + l = p + q
- s + l ≤ p + q
Show hintHide hint
Think about the condition for allowing movement.
4Question 4.
True or False: If a mechanism is Grashof type, it means all links can rotate indefinitely.
- True
- False
Show hintHide hint
Focus on the meaning of Grashof type.
Question 5.
Design a four-bar linkage with the following lengths: s=2, l=6, p=4, and q=3. Test if it is Grashof type, then calculate what changes could make it Grashof type if it isn't.
Show hintHide hint
Revisit the length relationships.
Question 6.
Evaluate a slider-crank mechanism's angle efficiency at a transmission angle of 30°. What adjustments would you recommend for better performance?
Show hintHide hint
Consider ideal angles and their role in mechanical efficiency.
